É quase um consenso que os planetas ao serem formados, nasceram com obliquidades quase nulas. No entanto, para os planetas gigantes, exceto Júpiter, as atuais obliquidades estão longe de zero. Para Saturno, Urano e Netuno ...

The rotational motion of an artificial satellite is studied by considering torques produced by gravity gradient and direct solar radiation pressure. A satellite of circular cylinder shape is considered here, and Andoyers ...

A first order analytical model for a general problem of artificial satellite's attitude corrections maneuvers submitted to gravity gradient torque is presented in this paper. It is assumed that the satellite is a rigid ...

A semi-analytical approach is proposed to study the rotational motion of an artificial satellite, under the influence of torque due to the solar radiation pressure, and taking into account the influence of Earth's shadow. ...

The dynamics of the rotation of a satellite is an old and classical problem, specially in the Euler formalism. However, with these variables, even in torque free motion problem, the integrability of the system is far from ...

A first order analytical model for optimal small amplitude attitude maneuvers of spacecraft with cylindrical symmetry in an elliptical orbits is presented. The optimization problem is formulated as a Mayer problem with the ...
